【Durable Material】:High quality PA66 plastic plus GF30% is selected, which is resistant to high temperature, oil, aging, impact, deformation and embrittlement during long-term use. NBR is used as the sealing element, which has good elasticity and small compression permanent deformation. It perfectly fits the cylinder head sealing surface to prevent oil leakage and oil and gas leakage.
【High Pressure Seal】:Accurately maintain a slight negative pressure in the crankcase, protect the oil seal, prevent oil leakage, prevent gas leakage, improve idle shaking, and accelerate more smoothly
